Data are summarized as the mean ± standard deviation or median (interquartile range) for normally or non-normally distributed continuous variables and as the number with proportion for categorical variables. ANOVA and Kruskal-Wallis test were used for continuous variables, and the Pearson χ2 test was used for dichotomous variables.
